Can calories from ethanol contribute to body weight preservation by malnourished rats?

Our objective was to compare the use of calories from ethanol by well-nourished and malnourished rats in terms of body weight. Female Wistar rats weighing 170-180 g at the beginning of the study were used. The animals were divided into two groups (N = 12 each): group W received water ad libitum and group E an ethanol solution ad libitum as the only source of liquid throughout the experiment. The concentration of ethanol was increased weekly from 0 to 5, 10, 20 and 40% (v/v). In the well-nourished phase (A), all rats received food ad libitum (AW and AE). Ethanol treatment (AE) was then interrupted and water was offered to both groups. After 2 weeks both AW and AE rats were submitted to food restriction (50% of group AW food consumption), thus initiating the malnutrition phase (M). Liquid was offered as described before to the same W (MW) and E (ME) groups. The weight gain during the 1-week treatment of AE rats was similar to that of AW animals only when AE rats received the 5% (v/v) ethanol solution (9.16 vs 10.47 g). Weight loss was observed after exposure to 10% ethanol (P < 0.05) in spite of maintenance of caloric intake. Malnourished rats presented weight loss, which was attenuated by ethanol intake up to the 20% (v/v) solution and was related to an increased caloric offer. This effect was not observed with the 40% ethanol solution (-9.98 g). These data suggest that calories from ethanol were used to maintain body weight up to the concentration of 10% (v/v) (well-nourished) and 20% (v/v) (malnourished) and that ethanol has a toxic profile which depends on nutritional status.

Preservation of graft function in low-risk living kidney transplant recipients treated with a combination of sirolimus and cyclosporine

The use of sirolimus (SRL) in combination with full doses of cyclosporin A (CsA) results in reduced one-year kidney allograft function, which is associated with shorter long-term allograft survival. We determined the effect of reduced CsA exposure on graft function in patients receiving SRL and prednisone. Ninety recipients of living kidney transplants receiving SRL (2 mg/day, po) were compared to 35 recipients receiving azathioprine (AZA, 2 mg kg-1 day-1, po). All patients also received CsA (8-10 mg kg-1 day-1, po) and prednisone (0.5 mg kg-1 day-1). Efficacy end-point was a composite of biopsy-confirmed acute rejection, graft loss, or death at one year. Graft function was measured by creatinine, creatinine clearance, and graft function deterioration between 3 and 12 months (delta1/Cr). CsA concentrations in patients receiving SRL were 26% lower. No differences in one-year composite efficacy end-point were observed comparing SRL and AZA groups (18 vs 20%) or in the incidence of biopsy-proven acute rejection (14.4 and 14.3%). There were no differences in mean ± SD creatinine (1.65 ± 0.46 vs 1.60 ± 0.43 mg/dl, P = 0.48) or calculated creatinine clearances (61 ± 15 vs 62 ± 13 ml/min, P = 0.58) at one year. Mean ± SD delta1/Cr (-11 ± 17 vs -14 ± 15%, P = 0.7) or the percentage of patients with >20% (26 vs 31%, P = 0.6) or >30% delta1/Cr (19 vs 17%, P = 1) did not differ between the two groups. The use of 2-mg fixed oral doses of SRL and reduced CsA exposure was effective in preventing acute rejection and preserving allograft function.

Random-start controlled ovarian stimulation for emergency fertility preservation in a patient with myelodysplastic syndrome: a case report

This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS) who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is also provided. A 17-year-old patient was diagnosed with MDS and required initiation of peripheral blood stem cell transplantation within a maximum of 3 weeks and was in the luteal phase of the menstrual cycle when the possibility of attempting preservation of fertility was presented to her. She opted for a random-start controlled ovarian stimulation with gonadotropins. With successful hemorrhagic prophylaxis, 17 oocytes were retrieved including 10 mature and 7 immature oocytes. Of the immature oocytes, 3 were successfully matured in vitro and a vitrification protocol was used to freeze the 13 mature oocytes.

Quality of Canned mandarin as affected by preservation liquid

This study is integrated within a research line dedicated to evaluate different options to introduce mandarin in Spanish agro-food industries and in both national and international markets. The effects of different preservation liquids (sucrose solution, sucrose and ascorbic acid solution, grape, and grapefruit juices), soluble solids (10, 12, 14 ºBrix), and thermal processing (30 seconds at 98 ºC) on vitamin C, color, carotenoids and sensory quality of canned Satsuma mandarin segments were studied. The liquid preservation that presented the best results was grapefruit juice, which provided the highest vitamin C (323 mg.L-1) and total carotenoids (16.4 mg.L-1) contents (the main carotenoid found was β-cryptoxanthin), intense orange color, high thermal stability, and very good sensory quality (e.g. intense floral and fresh-mandarin aromas and low levels of off-flavors).

Preservation of Agricultural Lands Society (PALS) fonds, 1954-2015, n.d.

Preservation of Agricultural Lands Society [PALS] held its first meeting at Brock University on June 21, 1976. Its first executive consisted of Robert Hoover, Rick Teather, Debbie Kehler and Bill Forster. Some objectives of the organization were "to seek the preservation of valuable farm areas from non-agricultural expansion and development and to foster development and support of federal, provinicial and local policy which will provide a secure financial future for farming." Gracia Janes and John Bacher are some of the organizations' well known advocates. The organization was active in raising public awareness of the issues surrounding encroaching development onto existing agricultural lands. The organization is still active today [2016] in educating the public and attempting to influence governments at all levels to protect valuable agricultural lands.

Tables de concertation et préservation du patrimoine, solution porteuse ou chimère ? : deux cas d’étude, le Vieux-Montréal et le mont Royal

La concertation est un phénomène récent, de plus en plus répandu. Elle s’applique à de nombreux domaines notamment en urbanisme et plus récemment à la protection du patrimoine. Elle semble être un outil approprié pour les autorités municipales afin de faire face aux conflits autour des projets d’aménagement particulièrement ceux liés à la protection du patrimoine. Notre questionnement porte sur l’apport de la concertation dans le domaine de la préservation du patrimoine et sur la pertinence des moyens mis en place pour atteindre un tel objectif. Les tables de concertation, en tant que processus de concertation, sont-elles appropriées pour la gestion des sites patrimoniaux ? À la lumière d’une discussion théorique sur le concept de la concertation en aménagement, nous faisons l’analyse comparative de deux Tables de concertation, celle du Vieux-Montréal et celle du Mont-Royal. Notre analyse porte sur l’évaluation du processus de concertation et sur la construction d’une vision globale pour le devenir des secteurs patrimoniaux concernés. L’objectif est de caractériser le processus de concertation utilisé à Montréal et d’en apprécier l’apport dans le domaine de la protection du patrimoine. L’analyse de nos deux cas d’étude révèle l’existence d’un processus de concertation propre à Montréal, avec ses caractéristiques spécifiques, mais qui reste à parfaire pour son optimisation. Notre recherche se conclut sur la nécessité d’améliorer le processus de concertation, tel qu’étudié, à travers un certain nombre de pistes à explorer.
